Transcutaneous Auricular Vagus Nerve Stimulation to Improve Emotional State
BiomedicinesEmotional experiences are a part of our lives. The maladaptive functioning of an individual’s emotional field can lead to emotional disturbances of various kinds, such as anxiety and depression.

Transcutaneous Vagus Nerve Stimulation Enhances Probabilistic Learning. [PDF]
PsychophysiologyABSTRACT tVNS enhances various memory and learning mechanisms, but there is inconclusive evidence on whether probabilistic learning can be enhanced by tVNS. Here, we tested a simplified version of the probabilistic learning task with monetary rewards in a between‐participants design with left and right‐sided cymba

Transcutaneous vagus nerve stimulation improves interoceptive accuracy [PDF]
Neuropsychologia, 2019 How can interoceptive accuracy, i.e. the objective ability to identify interoceptive signals, be improved? In the present study, we investigated whether non-invasive stimulation of the auricular branch of the vagus nerve (taVNS) modulates cardiac interoceptive accuracy, interoceptive sensibility, i.e. confidence in the identification of bodily signals,

Brain–Heart Interaction During Transcutaneous Auricular Vagus Nerve Stimulation [PDF]
Frontiers in Neuroscience, 2021 ObjectivesTranscutaneous auricular vagus nerve stimulation (taVNS) modulates brain activity and heart function. The induced parasympathetic predominance leads to an increase of heart rate variability (HRV). Knowledge on the corresponding cortical activation pattern is, however, scarce.

Non-invasive Autonomic Neuromodulation Is Opening New Landscapes for Cardiovascular Diseases
Frontiers in Physiology, 2020 Autonomic imbalance plays a crucial role in the genesis and maintenance of cardiac disorders. Approaches to maintain sympatho-vagal balance in heart diseases have gained great interest in recent years.

Transcutaneous Electrical Stimulation of the Abdomen, Ear, and Tibial Nerve Modulates Bladder Contraction in a Rat Detrusor Overactivity Model: A Pilot Study [PDF]
International Neurourology Journal, 2023 Purpose The global prevalence of overactive bladder (OAB) is estimated at 11.8%. Despite existing treatment options such as sacral neuromodulation, a substantial number of patients remain untreated. One potential alternative is noninvasive transcutaneous

Transcutaneous vagus nerve stimulation (tVNS) enhances divergent thinking [PDF]
Neuropsychologia, 2018 Creativity is one of the most important cognitive skills in our complex and fast-changing world. Previous correlative evidence showed that gamma-aminobutyric acid (GABA) is involved in divergent but not convergent thinking. In the current study, a placebo/sham-controlled, randomized between-group design was used to test a causal relation between vagus ...

Transcutaneous vagus nerve stimulation (tVNS) modulates flow experience [PDF]
Experimental Brain Research, 2017 Flow has been defined as a pleasant psychological state that people experience when completely absorbed in an activity. Previous correlative evidence showed that the vagal tone (as indexed by heart rate variability) is a reliable marker of flow. So far, it has not yet been demonstrated that the vagus nerve plays a causal role in flow.

Auricular transcutaneous vagus nerve stimulation modulates the heart-evoked potential [PDF]
Brain Stimulation, 2022 There is active interest in biomarker discovery for transcutaneous auricular vagus nerve stimulation (taVNS). However, greater understanding of the neurobiological mechanisms is needed to identify candidate markers. Accumulating evidence suggests that taVNS influences activity in solitary and parabrachial nuclei, the primary brainstem relays for the ...
